What is JavaScript?
JavaScript is a very powerful client-side scripting language. JavaScript is used mainly for enhancing the interaction of a user with the webpage. In other words, you can make your webpage more lively and interactive, with the help of JavaScript. JavaScript is also being used widely in game development and Mobile application development.
This document provides an overview of JavaScript, including:
- JavaScript is a client-side scripting language designed for web pages that enhances HTML with dynamic and interactive features.
- It was initially developed by Netscape as LiveScript but was renamed JavaScript and standardized along with Java.
- JavaScript can react to events, validate data, detect the browser, create cookies, and read/write HTML elements.
- Key JavaScript concepts covered include objects, properties, methods, functions, values, variables, and the HTML DOM for finding and manipulating elements.
JavaScript is a scripting language originally designed for web browsers but now used everywhere. It has dynamic typing and supports object-oriented, imperative, and functional programming. JavaScript was created in 1995 and standardized in 1999. It is now the most popular language on GitHub. JavaScript can be used to build interactive web pages, desktop applications, server-side applications, IoT applications, and real-time applications. The core data types in JavaScript are Number, String, Boolean, Object, Function, Array, Date, and Regular Expressions. JavaScript supports features like variables, flow control, error handling, debugging, and JSON for data exchange.
This document provides an introduction to jQuery, including:
- jQuery is a JavaScript library that simplifies HTML document interaction and event handling. It was created by John Resig in 2006.
- The current version is 1.3.2 and version 1.4 is coming soon. John Resig continues to develop jQuery in Boston.
- jQuery selects elements, changes their properties, handles events, and makes AJAX calls to simplify common JavaScript tasks. It works by selecting DOM elements and running functions on the selection.
The document provides an overview of regular expressions (regex) in JavaScript, including syntax for patterns, anchors, quantifiers, groups, modifiers, and replacements. It also includes examples of using regex to find and replace patterns in text, and practices applying regex to tasks like changing URLs, incrementing IDs, and reformatting dates.
The document discusses the Document Object Model (DOM), which defines the logical structure of objects in an HTML document and how they can be manipulated with JavaScript. The DOM represents an HTML document as nodes and objects that can be accessed and modified with JavaScript. All HTML elements, text, and attributes can be accessed through the DOM to be modified, deleted, or have new elements created. Events allow scripts to run in response to user actions on a page.
This document provides an introduction and overview of Node.js and MongoDB. It discusses that Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine that uses an event-driven, non-blocking I/O model. It can be used for real-time applications and is well-suited for I/O-intensive applications. MongoDB is also introduced as a popular JSON-based NoSQL database that can be easily used with Node.js applications. Examples are given for connecting to MongoDB from Node.js code.
This document provides an overview of PHP and MySQL. It defines PHP as a server-side scripting language that is commonly used with MySQL, an open-source database management system. The document discusses key PHP concepts like PHP files, variables, operators, conditional statements, arrays, loops, and functions. It also covers form handling in HTML and PHP. The intended audience is users looking to learn the basics of PHP and how it integrates with MySQL for database management.
PHP is a server-side scripting language used to create dynamic web pages. It allows embedding PHP code within HTML pages and interacting with databases. Key elements of PHP include variables, control structures, functions, and sessions. Sessions store user data on the server instead of the client to avoid cookies and allow tracking users across multiple pages.
This document is a presentation about JavaScript that covers what JavaScript is, where it came from, and what it can do. It introduces JavaScript as a scripting language that is easy to use and learn and runs in web browsers. The presentation explains that JavaScript is unrelated to Java but borrows some naming conventions. It provides overviews of JavaScript basics like variables, operators, and functions, as well as more advanced topics like objects, events, and DOM manipulation.
What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.
The document discusses key features of ECMAScript 6 (ES6), including:
- Default parameters, template literals, multi-line strings, spread operator, and enhanced object literals which add concise syntaxes.
- Arrow functions which provide a shorter syntax for writing anonymous functions.
- Block-scoped constructs like let and const that add block scoping to variables and constants.
- Classes which provide a cleaner way to define constructor functions and objects.
- Hoisting differences between function declarations and class declarations.
- Using ES6 today by compiling it to ES5 using a tool like Babel.

However, it also notes disadvantages such as costly editing tools, only being supported by newer browsers, requiring long and complex coding, potential browser support problems, and unprotected source codes.
XHTML is the next generation of HTML that combines HTML and XML. It aims to replace HTML by being a stricter, cleaner version that conforms to XML standards. Key differences from HTML include elements must be properly nested, documents must be well-formed, tag names must be lowercase, and all elements must be closed. There are three document type definitions for XHTML: Strict, Transitional, and Frameset.
The document discusses XHTML 1.0, which is an XML-based markup language that extends HTML. It defines XHTML as a family of current and future document types that reproduce, subset, and extend HTML 4. The document outlines the rules for XHTML documents, provides an example of valid XHTML code, and describes various elements and tags that can be used in XHTML such as links, images, lists, and tables.
This chapter introduces XHTML and covers:
- The transition from HTML to XHTML and XML syntax requirements
- The anatomy of a web page including head, body, and DTD sections
- Common inline and block-level tags for formatting text and elements
- Special characters and how to display them
- Creating hyperlinks within and between pages using absolute and relative linking
Dynamic HTML (DHTML) uses a combination of technologies including HTML, CSS, DOM, and scripting to create interactive and animated web pages. It allows changing tags, properties, fonts, and positioning in real-time. DHTML is useful for animating elements, embedding tickers, processing forms without server requests, and including drop-downs. The DOM represents page elements as objects that can be manipulated by scripts. Dynamic styles and data binding also allow quick updates without reloading content. While powerful, DHTML requires complex coding and editing tools and can have browser compatibility issues.
This document summarizes Chapter 15 of a Prentice Hall book on Dynamic HTML. It discusses various image filters and transitions that can be used to create special effects, including flip filters to mirror images, the chroma filter for transparency effects, masks to create transparent areas, and filters for inverting, grayscaling or applying x-ray effects to images. It also covers the glow, shadow and alpha filters for text effects and gradients, and transitions like revealTrans for animated page changes. The chapter objectives are to learn how to use and combine filters for effects and create animated visual transitions between web pages.
This document provides an overview of dynamic HTML (DHTML) and its components. DHTML uses HTML for content, CSS for styling and presentation, and scripting languages to manipulate and change the page after it loads. The three components are linked via the Document Object Model (DOM), which provides a standard interface. DHTML allows creating animations, games and applications by dynamically building web pages without plugins. It makes the web experience more interactive for users.
This document discusses algorithms and programming. It begins by defining an algorithm as a finite set of steps to solve a problem. It provides examples of algorithms to find the average of test scores and divide two numbers.

The document then discusses programming, explaining how to analyze a problem, design a solution, code it, test it, and evaluate it. It provides tips for writing clear, well-structured programs.
JavaScript has dynamic types where variables can change type, like a variable starting as undefined then being set to a number or string. It supports basic types like strings, numbers, booleans, and arrays. Arrays can be accessed and modified using methods. Objects are used to group related data and code, and functions are code blocks that execute when called. Namespaces and immediately invoked function expressions can help organize code and provide privacy.
This document provides an overview of JavaScript basics including data types, dynamic typing, strings, numbers, Booleans, arrays, objects, functions, scope, and common patterns like namespaces, modules, and immediately invoked function expressions (IIFEs). It covers topics like primitive vs reference types, type coercion, equality operators, object literals, constructors, and the revealing module pattern for encapsulating code.
This document provides an overview of JavaScript concepts and best practices. It discusses objects as hashes, functions as first-class objects, loose typing, closures, prototypes, JSON, cross-domain AJAX, testing with Jasmine, CoffeeScript, libraries like jQuery, global scope issues, regular expressions, XSS, hoisting, and other JavaScript quirks. It also provides resources for further learning JavaScript.
JavaScript is the world's most popular programming language. It is used to add interactive effects to web pages. JavaScript code can be inserted into HTML pages between <script> tags. Common JavaScript statements include conditional statements like if/else and loops. Variables are used to store and manipulate data in JavaScript. Common data types include strings, numbers, booleans, arrays, and objects. Functions allow code reuse and organization. Operators are used to assign values, compare values, and perform arithmetic. jQuery is a popular JavaScript library that simplifies DOM manipulation and event handling.
Javascript is actually called ECMAScript.

HSCIC/ESR Data Quality / Data Standards Road Shows 2015/16
The Health and Social Care Information Centre has hosted a series of road shows jointly with the Electronic Staff Record (ESR) Central Team and Health Education England to highlight developments in NHS workforce information, data standards and data quality.
Here are the slides presented at the fourth event, held at the Taunton Rugby Club, Taunton on 25th February 2016.
Data quality is all about collaborative working with a shared purpose and this is the main driver behind our road shows during 2015/16. Any efforts to improve data quality should have mutual benefits and should provide a platform for discourse between all involved. Collectively we can ensure that the data that is used to inform decisions about the workforce at local, regional and national level is as accurate as possible. Good data quality can't guarantee good decisions are made, but poor data quality will definitely increase the likelihood of poor decisions and poor outcomes.

Data quality is all about collaborative working with a shared purpose and this is the main driver behind our road shows during 2015/16. Any efforts to improve data quality should have mutual benefits and should provide a platform for discourse between all involved. Collectively we can ensure that the data that is used to inform decisions about the workforce at local, regional and national level is as accurate as possible. Good data quality can't guarantee good decisions are made, but poor data quality will definitely increase the likelihood of poor decisions and poor outcomes.
The document outlines the agenda for a data quality and data standards roadshow presented by the Health and Social Care Information Centre. Recent developments in NHS Jobs data quality and the workforce Minimum Data Set are discussed, including issues found and future plans. Future proposed changes to national workforce data standards and codes are also mentioned.
The purpose of this case study summary is to briefly describe how stakeholders have used the prescriptions dispensed in the community publication to inform analytical, reporting and contract negotiation activities.

Nicholas Oughtibridge (Principle Author of the Code of Practice for Confidential Information - HSCIC) spoke at the recent "Commissioning in Healthcare show (CiH 2015)".
Areas covered include:
· The role of the code of practice
· What is covered by the Code of Practice on Confidential Information?
· The seven steps in the life of a data collection
· Sharing confidential information with other people to meet legitimate needs
· Plans for revising the Code of Practice on Confidential Information
Julie Henderson (Head of Analytical Services - HSCIC) presented with Shaun Rowark (Technical Analyst, Quality Standards - NICE) at the recent "Commissioning in Healthcare show (CiH 2015) ".
Areas covered include:
· NICE quality standards: These are concise sets of prioritised statements designed to drive measurable quality improvements within a particular area of health or care. Derived from the best available evidence, they can enable commissioners to be confident that the services they are purchasing are high quality, cost effective and focused on driving up quality.
· Real life examples of how quality standards are being used by commissioners, possible barriers to implementation and advice on how to overcome these
· Data available from the HSCIC and how to use these to support the commissioning process
The Intelligent Data Tool (IDT) analyzes data from 14 million annual NHS Pathways calls to provide intelligence about symptom prevalence, performance, and service usage. It turns call data into dashboards that empower commissioners to manage 111/999 contracts by providing filters, symptom trends, and performance management summaries. The IDT is currently in beta testing and will provide wider access if the pilot is successful.
Andy Williams (Chief Executive - HSCIC) spoke at the recent "Healthcare Efficiency Through Technology Expo (HETT 2015)".

· How does the mass media agenda drive content consumption?
· How has the move to ‘mobile’ changed the demand for information?
· Where next for online information and transactions?
The document summarizes key findings from the 2014-15 Adult Social Care Outcomes Framework annual report. It found that the North East and South East of England had the highest social care-related quality of life scores, while London had the lowest. Overall, 77% of social care service users felt they had control over their daily lives. Several metrics showed declines from 2012-13 to 2014-15, including carer-reported quality of life (from 8.1 to 7.9), carer satisfaction with social services (from 43% to 41%), and the proportion of carers who found it easy to access service information (from 69% to 66%).
